Ok I tried your plugin on a pre-goldrush listenserver.

The only thing I changed were the weapons:

#include <sourcemod>
#include <tf2_stocks>
#include <tf2>
public Plugin:myinfo = 
{
 name = "AwesomeWeps",
 author = "Upholder of the [BFG]",
 description = "Gives you awesome weapons.",
 version = SOURCEMOD_VERSION,
 url = "http://www.sourcemod.net/"
};
 
public OnPluginStart()
{
 RegAdminCmd("sm_awesomeweps", Command_Awesomeweps, ADMFLAG_CHEATS);
}
public Action:Command_Awesomeweps(client, args)
{
 if (args < 1)
 {
  ReplyToCommand(client, "[SM] Usage: sm_awesomeweps <#userid|name>");
  return Plugin_Handled;
 }
 decl String:Arguments[256];
 GetCmdArgString(Arguments, sizeof(Arguments));
 decl String:arg[65];
 new len = BreakString(Arguments, arg, sizeof(arg));
 
 if (len == -1)
 {
  /* Safely null terminate */
  len = 0;
  Arguments[0] = '\0';
 }
 decl String:target_name[MAX_TARGET_LENGTH];
 decl target_list[MAXPLAYERS], target_count, bool:tn_is_ml;
 
 if ((target_count = ProcessTargetString(
   arg,
   client, 
   target_list, 
   MAXPLAYERS, 
   COMMAND_FILTER_CONNECTED,
   target_name,
   sizeof(target_name),
   tn_is_ml)) > 0)
 {  
  for (new i = 0; i < target_count; i++)
  {
   GiveWeps(client, target_list[i]);
  }
 }
 else
 {
  ReplyToTargetError(client, target_count);
 }
 
 return Plugin_Handled;
}
GiveWeps(client, target)
{
 TF2_RemoveAllWeapons(target);
 
 TF2_GivePlayerWeapon(target, "tf_weapon_knife");
 TF2_GivePlayerWeapon(target, "tf_weapon_flamethrower");
 TF2_GivePlayerWeapon(target, "tf_weapon_minigun");
 TF2_GivePlayerWeapon(target, "tf_weapon_sniperrifle");
 TF2_GivePlayerWeapon(target, "tf_weapon_pipebomblauncher");
 
 ReplyToCommand(client, "You have given awesome weapons."); 
}

Now I ran TF2, and used the command on myself, instantly TF2 crashes with the following error:
"Bad entity in IndexOfEdict() index -14106619 pEdict 00000073 sv.edicts 10D10010"

EDIT:
Ok, sourcemodversion = 2137
